My company is running an HP 9000/800 server using HP-UX 10.20. Every so often the T-1 connection in our WAN may go down or a Win '95 workstation may crash and the IP address the machine was using is now locked. Even after rebooting the workstation. It happens with static IP's and dynamically assigned IP's. When the server is rebooted everything goes back to normal. The only workaround we have come up with is assigning the machine a new IP address until the server is rebooted. The problem comes when we have a printer that is attached to a workstation and shared through the HP box. When we change the IP we have to change other config files as well. What a pain. Any idea on how to free the locked IP?
